“…In addition to the culturing conditions, low-cost substrates are highly important for cost-competitive microbial oil production [8,12]. In recent years, different sources derived from food waste as carrot and apple pomace [13,14], orange peels [15] or pumpkin peels wastes [16] have been used for yeast cultivation and lipids production. For example, Donzella et al [16] report the utilization of pumpkin hydrolysate by enzymes without adding nutrients as media for lipid production by Cutaneotrichosporon oleaginosum, allowing producing of 24 g/L of biomass with 29% of lipids accumulation.…”

Background Horticultural intensive type systems dedicated in producing greenhouse vegetables are one of the primary industries generating organic waste. Towards the implementation of a zero-waste strategy, this work aims to use discarded vegetables (tomato, pepper and watermelon) as feedstock for producing microbial oil using the oleaginous yeast Cryptococcus curvatus. Results The soluble fraction, resulting after crushing and centrifuging these residues, showed C/N ratios of about 15, with a total carbohydrate content (mainly glucose, fructose and sucrose) ranging from 30 g/L to 65 g/L. Using these liquid fractions as substrate under a pulse-feeding strategy with a concentrated glucose solution resulted in an intracellular total lipid accumulation of about 30% (w/w) of the total dry cell weight (DCW). To increase this intracellular lipid content, the initial C/N content was increased from 15 to 30 and 50. Under these conditions, the process performance of the pulse-feeding strategy increased by 20–36%, resulting in a total intracellular lipid concentration of 35–40% DCW (w/w). Conclusion These results demonstrate the potential of discarded vegetables as a substrate for producing bio-based products such as microbial oil when proper cultivation strategies are available.

“…Valorization of fruit waste, as low-cost oily feedstocks, fits in the scope of cheap and clean biodiesel production technologies. Grape [28] and apple pomace [29,30] are promising feedstocks for biodiesel production. Although there have been several studies about custard apple waste for biodiesel production [31,32]., the production is limited to tropical countries.…”

Apple pomace is a solid waste derived from the apple processing industry. To foster sustainability, the apple processing industry must implement the circular economy model of biorefinery and treat apple pomace as a valuable source of apple seed oil. The first time, this study dealt with the design, economic, and potential environmental impact assessment of biodiesel production using apple pomace as a source of apple seed oil. An Aspen Plus? and WAR? software were used to evaluate the designed biodiesel production. Supercritical CO2 extraction and methanolysis of apple seed oil, methanol recovery, and biodiesel separation were the main production steps. The production facility was assumed to process 24 tons of apple seeds daily. The total capital and production costs were 1.26 US$ million and 2.82 US$ million, respectively. If revenues from selling apple seed meal as cattle feed were included, a biodiesel price could be 0.39 US$/kg. The process was environmentally friendly when apple seed meal was not treated as waste.
